UMAG, Croatia (AP) Croatia's Borna Coric beat Marcel Granollers 6-3, 6-3 in hot and humid conditions on Tuesday to reach the second round of the Croatia Open.
Seventh-seeded Coric felt at home with the weather, converting four out of 11 break points and scoring 35 winners to defeat his Spanish opponent.
''Conditions were very tough, but I like to play when it's like this, when the ball and court is slow, so I have more time,'' Coric said.
He next faces Britain's Aljaz Bedene.
Sixth-seeded Philipp Kohlschreiber of Germany also advanced after saving five break points to beat Santiago Giraldo of Colombia 6-3, 6-2.
Kohlschreiber started slowly and faced two break points before stepping up his game at 3-3 in the first set, and going on to win five games in a row.
